So, my buddy takes his M3 with catless Xpipes and tune out for a little road trip when he needs his inspection done. Says never a problem and rarely do they ever even go near the exhaust. I think Texas is more focused on losing federal funding due to high pollution in the bigger cities and not so much in the small towns where readings are never taken for federal standards.
Can someone else verify?
I think there is an issue with doing that if your car is registered in a non-attainment area (such as the DFW metroplex). There's quite a bit of info on DFW Auto Club
. Here's a link to a "state inspection" search on DFW AC: http://www.dfwautoclub.com/forums/se...earchid=251616
It looks like the search link has expired. Just search on "state inspection" on the DFW AC site
. There are several relevant threads.
